Here's an imagination exercise:
A young Donald Trump is a member of his college cheerleading team. In all of his off campus social media posts and face to face interactions he foments dissent within the team by lying, pitting people against each other, and in general acting in a very insubordinate manner. All of this is done very publicly. It doesn't take a lot of imagination to see how destructive Trump's behavior could be to the effectiveness of his cheerleading team. Should he be suspended from the team for the rest of the semester?
This young woman said something to the effect of "Fuck cheer. Fuck this school, Fuck this, Fuck that, etc, etc." Make no mistake about it, this young amateur did not accomplish the sort of disruption that we imagine in the above scenario, but she did openly try to foment dissent or at least try to do some sort of harm to the team.
There is the issue of scale, but both actors are trying to harm the school. It's not the same as her speaking out in support of an unpopular cause such as protesting a war.
